The role of quasi-static methods for gust loads analysis in the design and certification process is well established for conventional aircraft. In recent years, many novel configurations have surfaced with unconventional and nonlinear behavior. These unique characteristics might not be captured with quasi-static analysis, so quasi-static methods should be re-evaluated before they are used to analyze any novel application. Two such applications are considered in this paper: a flying wing high

It will be shown that quasi-static methods may be useful for preliminary design of the joined wing aircraft, but will not be robust enough for detailed design or certification of the either application.
